South Sudan 'remains very volatile' - UN warns
Talks to end the fighting in South Sudan have opened in the Ethiopian capital, Addis Ababa.
Negotiators for the government and rebel sides have been meeting mediators but have not yet met face-to-face.
Meanwhile, the UN is warning that the situation remains very volatile and people caught up in the conflict in Bor are in dire need of food, water, sanitary facilities and medical supplies.
Toby Lanzer, from the UN peacekeeping mission in South Sudan, said: "The situation continues to be very very volatile - it's making it increasingly difficult for civilians."
